iMacros EditorThis release includes the new iMacros Editor with iMacros syntax highlighting, line numbers, and several other features for editing macros. The iMacros Editor is now the default editor launched when you select a macro to be edited from the iMacros sidebar.

Revised Scripting InterfaceThis release also includes the much anticipated revamped scripting interface, which overcomes a bug introduced in Firefox 3.6.x.

We have rewritten our Firefox driver to work around the Firefox bug and at the same time improved speed and reliability. Improved reliability means in this case that iMacros handles Firefox quirks better.

The result is that iMacros can now fully automate all Firefox versions, including the latest Firefox 4 Beta.
